:and other materials.

The constructionis such as to produce a thorough mixture of the ingredients, and the machine comprises a crusher which is employed in connection with one of the hoppers, which enables one of the ingredients to be crushed as the mixing takes place. The construction involves e tumbling barrel which receives the ingredients to be mixed, and this barrel is rotated continuously in an inclined position. so as to bring about a thorough mixture oi the different ingredients. An arrangement is provided for adjusting the angle or inclination of this barrel so as to produce a more or less rapid operation of the machine.

The invention consists in the construction and combination of parts to he more fully described hereinafter and particularly set forth in the claims.

Reference is to he .had to the accompanying drawings forming a par of this specification, in which similar characters of reference indicate corresponding parts all the figures.

Figurel is a perspective of a machine constructed according to in nvention; Fi E2 is e side elevation of the machine showing the side opposite from that which is shown iii, F 1; Fig. 2 is s fragmentary view illustrating the means for supporting the lower end of the barrel, and showing the means for adjusting the seineil ig. 3 is i plan of one end of the machine showing; the hoppers and the detai s oithelr construction, this viewalso shows portion of the barrel; and Fig. is s ve' ticel section. through the parts or the machine shown in Fig. 3, and taken substantially on. the line 1 represents the main ironic the machine formed thereupon.

w ich is supported on wheels 2,115 indicated. This frame comprises four corner posts or standards 3 which support an upper frame 4. The horizontal bars 5 and 46 of this upper frame support a horizontal main shaft 6 which extends transversely of the frame, and passes under three hoppers 6, T, and 8. Beneath the hoppers the shaft is provided with drum 9 which forms the bottom for the hoppers, as indicated most clearly in 4. The hoppers T and S are constructed as divisions formed in a larger hopper by, means of a partition wall 10. The hopper 6 is divided from the hoppers 7 and S by a dividing wall 11, as shown. This dividing wall is provided at its lower edge with open ings 12 lying adjacent to the drum 9, and these openings are adapted tohe-closed by gates 13 which slide in suitable guides 1 These are adapted to be operated from a point above the hoppers by means of handles 15 attached to stems 16, as shown. On the forward wall 17 of the hopper 6, with respect to the direction of rotation, an opening 18 is provided, similar to the openings 12, and this opening is similarly provided with a sliding gate 19 provided with a stem 20 having a handle 21 disposed above the hopper. v

The drum 0 constitutes teed drum, and advances the ingredients oi the mixture from (he hoppers into a tuinhlino harrel 22. This barrel is in the form of n liOllOW inder, its upper end forn'iin an open. mouth into which the drum 5) projects, as indicated in Fig. 4-. This tumbling barrel support-. ed on a swing or tilting cradle formed of side bars 2% which are connected by cross bars 25. These cross bars 25 are provided with rollers 26, and these rollers on collars 2i and 28 which encircle barrel. The collar 28 is located near the upperend of the barrel, and has a bevel gear wheel. 2h

This bevel gear wheel 29 projects iaterally from the drum. so as to form 2. shoulder 30, and the brackets 31 which so the rollers 28 at this point er provided with small rollers 32 which roll on thisshoulder and prevent the barrel from slidii'ig longitudinally down the barrel rotated continuously by means of. this gear wheel. 29, whico. meshes with adriving wheel 33 which rigidly mounted upon the main sh 6 es shown.

in the lower port of the hoppers 7 and 8, stirrers 34} are provided which consist of coils should come between the fil'lgel'b. lVith this of wire attached to a horizontal-shaft 36 l same diameter which passes through the hoppers at this point. These stirrers operate to agitate the material in the lower part of the hoppers so as to assist its being fed through the openings 12.

In the lower portion of the hopper 6 a crusher shaft 37 is mounted in a horizontal position, and this shaft is provided with a crusher 38, said crusher being composed of a plurality of closely disposed finger plates 39. Each of those plates 39has four substantially radially projecting fingers 40. This crusher is driven continuously when the machine is in operation, and as it rotates, the fingers 40 pass between parallel fingers 41 which project toward the crusher and form agrate 42. These fingers 41 are all attached to a grate shaft43 which is also in a horizontal position and disposed parallel with the shaft 87 The grate shaft 43 has a reduced extension which projects through the side wall of the hopper and carries a rigid arm 44. To the end of this arm 44 a link 45 is attached, and the lower end of this link 45 is connected with a frame bar 46 by a coil spring 47. As shown in Fig. 4, the fingers 41 of the grate incline downwardly so that they do not project directly toward the shaft 3 When the machine is in operation, the material which is to be crushed is fed into the hopper 6 so that it will be ground between the fingers 40 and 41 as the crusher rotates. The spring 47 is utilized so as to give resiliency to the grate and to permit its fingers to be deflected in case a large or hard lump arrangement instead of breaking any of the fingers of the crusher on the grate, the grate will simply become depressed so as to permit the lump to drop through.

I provide means for supporting the lower end of the cradle 23- at different elevations so as to adjust the inclination of the barrel, as indicated by the dotted. lines in Fig. 2. in Figs. 1 and 2, the lower end of the barrel is shown in its most depressed position; the end of the cradle 23 rests upon a horizontal cross bar 48 at the forward end of the frame. The vertical posts 3 at this end of the frame are provided with. a plurality of oppositely disposed openings 49, and these openings are adapted to receive the ends of a cross bar or rod 50, in the manner indicated in Fig. 3. This cross bar 50 may support the lower end of the cradle so as to changethe elevation of the barrel. at this point, as will be readily understood. In adjusting the barrel it is raised or lowered by hand.

The lower end ofthe barrel 22 is provided with a nozzle or muzzle 51 which is of substantially conical form and is made of wire gauze so asto constitute a screen. The upper end of this nozzle is of substantially the as the barrel so as to enable the nozzle to be attached, as shown. The lower extremity of the nozzle is of reduced diameter and is o Jen so as to provide a discl'large openin for the material whidh is mixed in the barrel.

The barrel 22 is provided on its inner side with longitudinally disposed strips or mixer bars 52 which may be formed of angle iron, as indicated. lVhen the barrel is rotating these mixers pick up the material and let it fall again so as to bring about a thorough mixture of the dil j'ercnt ingredients.

The shaft 6 is provided with a large belt wheel which is adapted to be driven continuously by a belt. This wheel is also provided with a crank 54 which enables it to be rotated by hand when desired. 236 and 37 extend through the walls of the hoppers (3 and 7 on the same side as shown, and these shafts are provided with sprocket wheels and 56,1'cspectively. The sprocket wheels are driven in the same direction by means of an endless sprocket chain 57 which runs over them, and which runs over a drivingisprocket wheel 58 which is attached to the shaft G From an observation of Fig. 2, it will be seen that the side bars 24 of the cradle 23 are substantially parallel with theaxis of ,the barrel, but at their upper endsth'ey have vertical extensions 59 which are pivotally attached to the shaft 6, as will be understood.

The upper frame 4 includes a landing frame (10 which is disposed near the hoppers, and. this frame may be utilized as a support for the materials which are to be mixed in the machine. It also a lt'ords a support from which the handles of the gates may be readily operated.

In the operation of the machine he drum.

S) is driven continuously in the direction of the arrow in Fig. 4, that is, its upper side rotates toward the barrel The ingredients which are fed into the hoppers (3, 7, and 8,

when the gates 13 and .19 are open, will therefore be advanced into the barrel. in

readily I The shafts i the barrel they become thoroughly mixed with each other. The -relative proportions of the ditl'erent ingredients can be regulated by regulatii'ig the distance to which the gates 13 and if) are raised. In other words, by regulating the amountof opening through which the hoppers deliver. of material to be mixed is great without requiring a very thorough mixing of the in-. gredients, then the barrel 22 will be greatly inclined, as indicated by the full lines in Fig. 2. If, on the other hand, a 'very thorough mixture is necessary,'the lower extremity of the barrel will be elevated to the highest possible point. In this way thematerial gravitating through the barrel moves slower and a very thorough mixture natu-- If the quantity 45. I v ,-in thc'lower portion rally results. the barrel reaches the screen 51, the smaller particles pass through the meshes of the screen, while the lamps which are too large pass out of the opening at the end of the nozzle.

he drum 9 may be made of any material desired, and it may be smooth or corrugated, When the machine is used for mixing fertilizers or similar materials containing acids, I prefer to form the drum of wood as it is not attacked by the acids. In mixing fertilizers the different hoppers canbe used for holding cotton seed meal, sodium phosphate, muriate of potash, nitrate of soda, dried blood, or any other chemical that may be used as a fertilizer.

The hopper 6 having the crushing mechanism is inten ed to be used for crushing phosphates or similar materials when the machine'is used for mixing fertilizers.

Special attention is called to the fact that the central axis of the barrel intersects the axis of the main shaft 6, which enables the gear wheels 29 and 33 to mesh with each otherin any of the adjusted positions of the barrel. On one of the cross bars of the upper frame a roller 22* is mounted that limits the upward adjustability of the barrel 22;
